Abstract

PURPOSE:To effectively check the functions of only required devices by storing test numbers of all output devices and inputting the test number of a test object and issuing a command for input/output check from a master to a carriedout slave with respect to the inputted test number. CONSTITUTION:When test numbers of input/output devices X, Y to be tested are inputted by a test number input means 3, a prescribed command signal is sent from a command output means 1B to a carried-out slave with respect to devices corresponding to test numbers stored in a storage means 1A. Then, input check and output check of the input device X and the output device Y are performed by a check means 2A. Operation conditions at this time are detected by an operation detecting means 1C; and when they are normal, a tone or the like is outputted by an output means 5. Thus, only required devices are checked to shorten the check time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input / output check function of a vending machine, and more particularly to an input / output check function applicable to a normal operation check check and a failure cause investigation.

[0002]

2. Description of the Related Art Conventionally, there are vending machines provided with an input / output check function, but the checking function is for comprehensive checking of vending machines, and therefore, the following points are defective.

[0003]

(1) Both the input and output check functions are checks for all loads, and it takes time because the minimum necessary checks cannot be performed.
In addition, it is difficult to understand the check result because all devices are subject to check. (2) The output check is wasteful because raw materials are discharged to actually operate the load. (3) If the number of check items increases due to new model development, etc., it cannot be easily handled. The present invention can perform a function check only for necessary equipment,
Moreover, it is an object of the present invention to provide an input / output check device that can be used in a short time without waste.

[0004]

According to the present invention, a master (1) that is a main control unit and a plurality of slaves (2,
In a vending machine with a system configuration distributed in 2 '),
Input devices (X) such as switches and output devices such as motors connected to the slave (2) for carrying out in the vending machine
A device for checking whether (Y) is functioning normally, and a storage means (1A) for storing test numbers assigned to all input / output devices (X), and a test target. Test number input means (3) for inputting a test number, display means (4) for displaying the test number input by the test number input means (3), and test number input means (3)
Command output means (1B) that issues a command to perform input / output check from the master (1) to the export slave (2) for the input / output device corresponding to the test number input in In response to the input check and output check commands, the input device (X) to be tested is turned on / off, and the check means (2A) for driving the output device (Y) for a certain time and the input device (X) The operation detecting means (1C) for detecting whether a normal signal is input to the carry-out slave (2) by turning on / off and the operation detecting means (1C) detects the input device. (X)
And an output means (5) for notifying that the normality has been detected.

[0005]

According to the above construction, when the test number of the input / output device (X, Y) to be tested is input by the test number input means (3), it corresponds to the test number stored in the storage means (1A). A predetermined command signal is sent to the device from the command means (1B) to the carry-out slave (2).
As a result, the corresponding input device from the checking means (2A)
(X) and output device (Y) are input check and output check, the operation status at that time is the operation detection means (1C)
If the operation is normal, the output means (5) outputs a sound, for example.

1 is a control block diagram showing an embodiment of the apparatus of the present invention. Reference numeral 1 denotes a master, which controls the carry-out slave 2 and other slaves 2 '. A storage unit that stores the test numbers assigned to all the input devices X and the output devices Y and the operation time (1 second in this embodiment) at the time of checking the output devices Y in the master 1. 1A, and a commanding means 1B and an operation detecting means 1C described later. 3 is a test number input means for inputting a test number of a device to be tested to all input / output devices X and output devices Y, and 4
Is a display means for displaying the test number input by the test number input means 3 for confirmation.

The command means 1B issues a command for the input / output check from the master 1 to the carry-out slave 2 for the test number input by the test number input means 3. The carry-out slave 2 is provided with a check unit 2B for turning on / off the input device X and driving the output device Y for a certain period of time by receiving the command. The operation detecting means 1C detects whether or not a normal signal is input to the carry-out slave by turning on / off the input device X, and 5 is detected by the operation detecting means 1C. Is a buzzer for notifying that the normality of the input device X has been detected, and corresponds to the output means.

An operation example of input / output check in the apparatus having the above-mentioned configuration will be described. Tables 1 and 2 show data of the test number for the input device X, the test number for the output device Y, and the operation time thereof, which are stored in the storage unit 1A.

[Table 2]

As an input check, a drain bucket and a dam S
When checking whether the input device X for switch input of W and gas pressure SW is normal, the test number input means 3 is used.
First, the "input check" key (not shown) is turned on to enter the input check mode, and then the test numbers for the input device X, "01", "02", and "03" are input in order. The entered test number is displayed on the display means 4 for confirmation. After inputting the test number of the desired input device, the "execute" key (not shown) is turned on, and the command output means 1
A predetermined command signal is sent from B to the check means 2A of the carry-out slave 2, whereby the drain bucket SW is first turned on / off, and the state change of the SW at this time is detected by the operation detection means 1C, and the SW The buzzer 5 sounds for 200 mS when changing from on to off and from off to on. Next, the dam SW is turned on / off in the same manner, and the buzzer 5 is rung when the state of the SW changes, and the input is checked one after another in this manner. At this time which SW
In order to know whether or not the check has been made for, the part of the relevant test number among the test numbers displayed on the display means 4 is displayed in reverse video, for example. When the input device X to be tested is checked, the "end" key (not shown) is turned on to end the input check mode.

Next, as an output check, the raw material motor 1,
In order to check whether the output devices Y of the raw material motor 2 and the raw material motor 3 are operating normally, the test number input means 3 first turns on the "output check" key (not shown) to enter the output check mode. Above, the test number for the output device Y, "01", "02", and "03" are sequentially input. In this case as well, the test number entered for confirmation is displayed on the display means 4. Then, by turning on the "execute" key, the raw material motor 1 is first operated for 1 second at a time, and during this period, it is visually checked to see if the output device Y to be tested is normally operating. Output device Y to be tested
When the check is completed, the "end" key (not shown) is turned on to end the output check mode.

[0013]

As described above, according to the present invention, since the input / output device to be tested can be set, the function check can be performed only on the necessary device, and the check time can be shortened. In addition, since the output devices are driven for a short period of time (1 second in the embodiment), the raw materials are not wasted at that time, and even when the number of input / output devices increases Can deal with
